To @ZZ whom, t may concern..-

Be it known that I, LOUIS HORN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Ball-Bearings, of which the following is a Specilication.

My invention relates to certain improvements in roller-bearings for use particularly in theh ubs of bicycle-wheels and in the crankhangers of the same, although it will be understood that myinvention can be used anyis an enlarged sectional View of a portion of Fig. l, and Fig. 5 is a View showing the parts illustrated in Fig. el detached.

A is the axle, secured in any suitable manner to the frame of the bicycle.` Each end of the axle is screw-threaded in the present instance, and adapted to each screw-thread is a cone-nut a of the form clearly illustrated in the drawings. Back of vthese cone-nuts are the ordinary nuts a' and washers for securing the axle to the frame A',

B is the hub, which may be either of the hollow form shown in the drawings or solid. The hub is recessed at each end, and adapted to each recess is a shell D. This shell has a concaved recess d, in which rests a sliding ring D'. This ring has a convex back and is free to slide within the annular concaved recess d. The central opening in the shell D is somewhat larger than the axle, so that the axle will not come into contact with the shell. In the present instance the outer portion of each end of the hub is screw-threaded, and adapted to the hub at each end is a cap E, having a concaved annular recess c similar to the recess d in the shell D, and in this recess slides a ring E', having a convexed back similar tothe ring DI Mounted in the space between the shell and the cap are two series of balls f and g, and between these balls is a ring I. This ring is somewhat less in width than the space, so that it runs freely between the two face-rin gs D and E and separates the series of balls, as indicated in the drawings. The balls f are in contact with the coneshaped nuts a of the axle, as shown, and carry the load.

I considerably reduce the friction of the parts by locating the outerseriesof balls between the ring I and the flange d o f the shell D, and I form on the shell an internal flange d2, as clearlyshown in Fig. 4, which extends beyond the face of the ring D', so that they space between this internal flange and the edge of the cap is less in diameter than the ball and prevents the inner row of balls from becoming detached from the shell and cap when the axle and its nuts are removed, but

- will not interfere with the free rotation of the constructionY and can 4be readily and cheaply i adapted to said recess, a cap having an annular recess at the side, a slide-ring adapted to said recess, two sets of balls mounted between the cap and the shell, and a loose ring mounted between the two sets of balls, substantially as described.

3. The combination of a hub, two shells, one in each end of the hub, caps forming with the shells, ball-spaces, two series of balls in each bal1-space, a separating-ring mounted between the two series of balls in each ballspace, an axle, and conical nuts adapted to the axle and against which the inner set of balls rest, substantially as described.

4. The combination of ashell having a central opening for the passage of an axle, a
